The story revolves around Theresa (Greene) and her group of friends who escape on an island destination weekend and find themselves unable to resist trying a new designer drug. The drug appears to be perfect. However, the group discovers its one major side effect: It makes people lose the ability to control their urges. Brosnan will play the creator and gatekeeper of the drug.

Greene, who is best known for playing Alice Cullen in The Twilight Saga, most recently was seen in Burying the Ex, which premiered in September at the Venice Film Festival. Past film credits include Wish I Was Here and Butter.

She is repped by CAA, McKeon-Myones Management and Gang, Tyre, Ramer & Brown.
